Method Detail

### generateEncryptionAlgID

    public static AlgorithmIdentifier generateEncryptionAlgID(ASN1ObjectIdentifier encryptionOID,
                                                              int keySize,

  Create an AlgorithmIdentifier for the passed in encryption algorithm.

  Parameters:
    `encryptionOID` - OID for the encryption algorithm
    `keySize` - key size in bits (-1 if unknown)
    `random` - SecureRandom to use for parameter generation.
  Returns:
    a full AlgorithmIdentifier including parameters
  Throws:
    `java.lang.IllegalArgumentException` - if encryptionOID cannot be matched
